Things You'll Need
Instructions
Double layer the wings, and make the outer edge a fold rather than a paper edge. This makes the wing stiffer and will improve its aerodynamics.
Make the body as small as possible and the wing as large as possible, while keeping both parts rigid.
Fold the body in multiple layers. This will make the body stiffer, and therefore it will fly faster and straighter.
Tape the halves of the body together so the plane is a "T" shape. If you double layered the wings, you can tape them together as well.
Use paperclips on the body to properly proportion the weight. The weight should be nearly even across the plane with a touch extra in the front third.
